INIPROVEIMENT IN MACHINES FOR- I DZRIIESSINGA IHOPPOLES The Schedule refenedto in these Letters Patent and making part of the leur-wV To all 'whoml it 'mc/y concern Be it known that I, C. D. BROWN, of Bainbridge, in the county of Ghenango, and State of New York, have invented a new and useful vImprovement iu Machines for Dressing Hop-Poles; and I do hereby declare that the following is a full, clear, and exact description thereof, which-will enable A others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part .of this specication, in which- Figure 1 is a side detail view of one of the cutter-wheels.

Figures 2 and 3 are, respectively, a side and edge view of the middle cutter-wheels.

Figure 4 is a side view of the remaining 'outside cutter-wheel.

Figure 5 is a front view of the three cutter-Wheels, when 'arranged on a driving-shaft for operation.

Similar letters of reference indicate like parts.

The object .of this invention is to provide a simple and effective means 'for sharpening and dressing hopoutside poles.

It consists inthe arrangement of three cutterfwheels on a shaft, in such a manner that the poles to. be sharpened or dressed may be passed between the said wheels and be cut by cutters or knives affixed on the radialv arms of the wheels, which latter are formed vwith ref-v erence to bearing the said knives, and presenting their cutting-edges to the wood in the most effective manner.

In the drawings, the form of the Wheels is shown, as also their position and arrangement when operating together as a machine.

Each wheel is composed of a rim and four radial arms, but, aside from these general features, differ essentially in construction.

-The iirst wheel, A, is the tapering o r sharpeningcutter wheel, having two ordinary arms, g, and two cutt'erebearing arms, c.

The cutter-bearing arms are bevelled to a'ord a proper surface for bearing the cutters, and presentirngv the edges of the same with the proper inclination to the pole to be dressed.

Each cutter may be in one cntinuous piece, or may I be in ,sectional parts,.and are to be bolted, or otherwise a'ihxed, on the bevelled arms of the wheels, in a radial arrangement corresponding to the said arms.

rlhe middle wheel B has four cutter-bearing arms, b d, the bevel of each of which being in an opposite direction from the adjacent two.

This arrangement enablestwo cutters to be aiiixed on each side of the wheel B, so that two shall operate in conjunction with the cutters on the approximate face of the adjacent outer wheels. f

The third and last wheel, C, has two bevelled cutter-bearing arms, e, and two plain arms, f, as shown.

When brought together on the same shaft, E, as shown at iig. 5, the relative arrangement of the bevelled arms will be such, that while the three wheels are revolving in the same direction, a hoppole, or other similar piece cf`wood, may be dressed, by passing. it

along on the table of the machine, and between the wheels B and C, for the cutters on the arms b and e will present their edges to the wcod,to dress each side of it, as the wood is passed along between the wheels. The taper is given to the-hop-pole by the cuttersvon the wheel A, for the arms of this wheel are tapered from 'the hub outward,as shown, so as to hold the cutter in a corresponding position by means of which the taper is given to one side of the end of the hoppole, as shown. The other side is dressed by the straight cutters on the wheel B.

A This action of the cutters leaves the hop-pole ta pered on one side of the end, which form 'is adapted for fitting in the staples, for it must be borne in mind that the hop-poles for which this machine is designed are aiiixed to a short post or stump by means of staples, the tapered part being next the side of the post which inc-lines the poles to the post in a manner resembling thebranches of a tree.

In operation, the poles are iirst passed singly between the wheels B and C to receive the proper smoothing or dressing on two sides.

dressed off on the remaining sides. 'lheends are then presented to the cutters of the wheels A and B, as shown, to receive the proper taper, as before described.

The wheels are driven by a belt on the pulley G of the shaft, which latter may have any suitable bearings 'in a frame or table, as in any other analogousl .and the cutters of steel, and of any `suitable form.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- .y

The construction of the three wheels A, B', yand C,

and their combination with and arrangementen the shaft E, substantially as herein shown and described.
